T0 (0 whom it may concern.-

Be it known I, JOHN KYNASTON, a subject of the Queen of Great Britain,residing in Liverpool, in the county of Lancaster, England, haveinvented certain new and useful Improvements in Machines for Looping andStitching Supporting-Tapes to Curtains or to Curtain-Heading Bands orthe Like, of which the following is a specification.

This invention relates to a machine for looping and stitchingsupporting-tapes to ourtains or to curtain-heading bands or the like. Inattaching curtains to the rings of the curtain-poles it is found thatthe curtains hang much more neatly and wear much better if the head ofthe curtain is provided with a looped tape by means of which theattachment is made to the rings, and which tapeis attached either to thecurtain directly, when the fabric is strong enough, or to a bandstitched to the curtain when the latter is woven openly, as in the caseof lace curtains. The tape requires to be attached to the curtains orthe curtainbands, as the case may be, at intervals, so as to form loopsfor attachment to the rings, or in the case of small curtains to the rodor string which supports the curtain; and the object of my invention isto provide a machine adapted to attach the tape at intervals to thecurtain or to the curtain-band or to attach both the tape and the bandto the curtains at the same time. The actual stitching is doneby asewing-machine the presser-foot of which is modified, as hereinafterdescribed, and a mechanism is provided by means of which the tape is atintervals withdrawn laterally from the line of stitching to form theloop.

I have illustrated my invention in the accompanying drawings inreference to a WVheeler & \Vilson sewing-machine. Only such portions ofthe machine are shown as are necessary to explain the action of theapparatus, and of course any other type of sewing-machine may beemployed.

Figure I is an elevation; Fig. II, a fragmentary end elevation Fig.III,'a perspective View showing the modification of the presser-foot,and Fig. 1V is a view showing the mode in which the band and the loopedtape are attached to the curtain.

which is provided with a slot 2, through which the heading-band 3 isguided, and a hole 4, through which the tape 5 (which in the presentcase is assumed to be of circular crosssection) is guided. Underordinary circumstances both the band and the tape would be stitched tothe curtain as they and the curtain are fed to the machine; but in orderto loop the tape it is further guided through a hole 6 in the lever 7.

The lever 7 is jointed to one end of a bellcrank lever 8, which ispivoted to the frame at 9. The other end of the bell-crank carries acam-roller 10, operated by a cam 11, carried on the worm-wheel 12, whichin turn is rotated by the worm 13, keyed to the shaft 14 of thesewing-machine. From an inspection of Fig. I it will be seen that thebellcrank lever is periodically oscillated by the cam and that as aresult the lever 7, and with it the tape 5, is drawn away laterally fromthe line of stitching, and a loop of the required length is therebyformed.

The lever? is pivoted so as to allow the toe of it to rise when thepresser-foot is raised, or the toe may be raised independently bydepressing the other end of the lever. The toe of the lever is pressedonto the presserfoot by a spring 15, and the bell-crank lever isprovided with a spring 16, which tends to keep the cam-roller in contactwith the cam.

It is to be understood that I do not limit myself to the precise detailsof the mechanism shown for withdrawing the tape, as it is obvious thatit may be modified to suit the particular kind of sewing-machine towhich 'it is attached.

In some cases I find it of advantage to use a machine with two needles,the one to continuously stitch the one edge of the band 3 to the curtainand the other to continuously stitch the other edge of the band to thecurtain, but to intermittently stitch the tape to the band and curtain.

The curtain, with the band and looped tape attached, is shown clearly inFig. IV.

Having now fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. In combination in a sewing-machine, a presser-foot provided with afixed tape-guide, a pivoted lever forming a movable guide for the tape,a spring for holding the latter guide in proximity to the former, asecond pivoted lever carrying the first lever, and means forintermittently oscillating said lever whereby the movable guide isshifted toward and from the fixed guide, substantially as described.

2. In combination, in a sewingmachine, a resser-foot provided with afixed tape-guide, a pivoted lever forming a movable guide for the tape,a lever pivoted to the sewing-machine head and carrying the first-nam edlever at its lower end, a spring connecting said levers and tending tothrow the guiding end of the first-named lever downwardly, and means foroscillating the second lever, substantially as described.

3. In combination, with a sewing-machine,

a bell-crank lever pivoted to the head thereof,

a spring acting on said lever, a cam operated JNO. KYNASTON.
